Although not actually streamed on liveatc.net, I thought I would let you guys know regardless...
The new tower at YKZ is now in use. This means that they have frequency coupling happening on ground/tower when only one controller is working.
If you hear ground comms. on the tower freq, or vise versa, this is the reason why.
124.8 Tower (119.9 backup)
121.8 Ground.
